  1. Which criterion should guide solutions for filtering muddy water for a soil investigation?

    • holds ten bikes securely in wind
    • removes the most visible particles in under two minutes
    • lowers noise while staying within budget
    • keeps seedlings between 15 and 25 degrees Celsius

  2. Which evidence is a strength of the coffee filter?

    • spreads force through the frame
    • raises soil temperature quickly
    • turns easily near shelves
    • catches fine soil particles

  3. Which tradeoff should engineers consider for the clear plastic cover?

    • can overheat plants on sunny afternoons
    • raises soil temperature quickly
    • protects seedlings without trapping as much heat
    • it has no constraints at all

  4. Which final design best uses evidence for keeping a model bridge from bending?

    • combine panels near classroom doors with simple route signs
    • add triangle braces under a thin deck
    • pour through mesh first, then a coffee filter
    • use a removable clear cover and vent it at midday

  5. Why compare soft wall panels and floor route signs before choosing?

    • criteria should be ignored
    • each solution may meet the criteria in different ways
    • tests cannot improve designs
    • the first idea is always best

  6. Which criterion should guide solutions for keeping a school garden bed warm on cold mornings?

    • removes the most visible particles in under two minutes
    • holds 2 kilograms using limited materials
    • keeps seedlings between 15 and 25 degrees Celsius
    • holds ten bikes securely in wind

  7. Which evidence is a strength of the thicker deck?

    • adds support under the load
    • spreads force through the frame
    • protects seedlings without trapping as much heat
    • catches fine soil particles

  8. Which tradeoff should engineers consider for the thicker deck?

    • it has no constraints at all
    • uses more material
    • adds support under the load
    • spreads force through the frame

  9. Which final design best uses evidence for moving library books without dropping them?

    • use a rolling bin with smaller sections and swivel wheels
    • combine panels near classroom doors with simple route signs
    • add triangle braces under a thin deck
    • use a removable clear cover and vent it at midday

  10. Why compare deep rolling bin and flat cart before choosing?

    • each solution may meet the criteria in different ways
    • tests cannot improve designs
    • the first idea is always best
    • criteria should be ignored
